Temptation in the Archives: Essays in Golden Age Dutch Culture

Temptation in the Archives is a collection of essays by Lisa Jardine, that takes readers on a journey through the Dutch Golden Age. Through the study of such key figures as Sir Constantjin Huygens, a Dutch polymath and diplomat, we begin to see the Anglo-Dutch cultural connections that formed during this period against the backdrop of unfolding political events in England. Temptation in the Archives paints a picture of a unique relationship between the Netherlands and England in the 17th century forged through a shared experience – and reveals the lessons we can learn from it today

Graph-Embedding Empowered Entity Retrieval

In this research, we improve upon the current state of the art in entity retrieval by re-ranking the result list using graph embeddings. The paper shows that graph embeddings are useful for entity-oriented search tasks. We demonstrate empirically that encoding information from the knowledge graph into (graph) embeddings contributes to a higher increase in effectiveness of entity retrieval results than using plain word embeddings. We analyze the impact of the accuracy of the entity linker on the overall retrieval effectiveness. Our analysis further deploys the cluster hypothesis to explain the observed advantages of graph embeddings over the more widely used word embeddings, for user tasks involving ranking entities

An investigation into the impact of question structure on the performance of first year physics undergraduate students at the University of Cambridge

We describe a study of the impact of exam question structure on the performance of first year Natural Sciences physics undergraduates from the University of Cambridge. The results show conclusively that a student's performance improves when questions are scaffolded compared with university style questions. In a group of 77 female students we observe that the average exam mark increases by 13.4% for scaffolded questions, which corresponds to a 4.9 standard deviation effect. The equivalent observation for 236 male students is 9% (5.5 standard deviations). We also observe a correlation between exam performance and A2-level marks for UK students, and that students who receive their school education overseas, in a mixed gender environment, or at an independent school are more likely to receive a first class mark in the exam. These results suggest a mis-match between the problem-solving skills and assessment procedures between school and first year university and will provide key input into the future teaching and assessment of first year undergraduate physics students.We would like to thank the Institute of Physics (IoP) for funding this research. We also gratefully acknowledge the support of the Cavendish Laboratory's undergraduate Teaching Committee, the markers of the exam scripts and the students who volunteered to undertake the mock exam.This is the final published version of the article.

'O decus Italiae virgo’ or, the myth of the learned lady in the Renaissance

Let me start by making it clear that, taken at face value, my title is entirely a piece of mischief: I am not about to disclose the fact that there were actually no learned women in Italy in the fifteenth century. Indeed, this paper is built around the careers and works of five distinguished women intellectuals of that period: Isotta Nogarola (1418–66); Costanza Varano (1426–77); Cassandra Fedele (c. 1465–1558); Laura Cereta (1469–99); and Alessandra Scala (1475–1506). There is, however, a serious point to my choice of words in the title. The point is that the ‘learned lady’ of the Renaissance (the cultivated noblewoman, beautiful, charming, gifted, ‘gentile’) has a mythic place in the secondary historical literature on humanism. From Isabella d'Este to Sir Thomas More's daughters and the English Tudor princesses, the cultivated gentlewoman is the Beatrice or the Laura of some male humanist's circle, his hi adoring pupil, his inspiration, his idol. Scholars adopt a fondly indulgent tone when discussing the women, which carries the implication that their intellectual calibre, their actual standing as scholars and humanists, is not a real issue, is perhaps not in fact of any real substance (a figment, rather, of their male admirers' or suitors' imaginations). The single scholarly piece of any significance on the life and work of Alessandra Scala concludes with typical sentimental indulgence:Her noble and elusive aspect – for no portrait of her survives, unless perhaps she smiles at us, unrecognised, in the guise of a saint or a goddess, from one of Botticelli's canvases, or that of some other Florentine artist – yet that aspect shines forth from the shadows of the past, and casts a beauteous and gracious light upon the discordant chorus of Florentine humanism at the end of the fifteenth century

Strategies for the discontinuation of humidified high flow nasal cannula (HHFNC) in preterm infants (Review)

BACKGROUND: Humidified high flow nasal cannula (HHFNC) delivers humidified gas at increased flow rates via binasal prongs and is becoming widely accepted as a method of non-invasive respiratory support for preterm infants. While indications for the use of (HHFNC) and its associated risks and benefits are being investigated, the best strategy for the discontinuation of HHFNC remains unknown. At what point an infant is considered stable enough to attempt to start withdrawing their HHFNC is not known. The criteria for a failed attempt at HHFNC discontinuation is also unclear

fMR-Adaptation Reveals Invariant Coding of Biological Motion on the Human STS

Neuroimaging studies of biological motion perception have found a network of coordinated brain areas, the hub of which appears to be the human posterior superior temporal sulcus (STSp). Understanding the functional role of the STSp requires characterizing the response tuning of neuronal populations underlying the BOLD response. Thus far our understanding of these response properties comes from single-unit studies of the monkey anterior STS, which has individual neurons tuned to body actions, with a small population invariant to changes in viewpoint, position and size of the action being viewed. To measure for homologous functional properties on the human STS, we used fMR-adaptation to investigate action, position and size invariance. Observers viewed pairs of point-light animations depicting human actions that were either identical, differed in the action depicted, locally scrambled, or differed in the viewing perspective, the position or the size. While extrastriate hMT+ had neural signals indicative of viewpoint specificity, the human STS adapted for all of these changes, as compared to viewing two different actions. Similar findings were observed in more posterior brain areas also implicated in action recognition. Our findings are evidence for viewpoint invariance in the human STS and related brain areas, with the implication that actions are abstracted into object-centered representations during visual analysis

Framing a bilateral US-Russian geologic repository initiative

This document summarizes a framework for the development of a bilateral United States�Russian geologic repository initiative to enable cooperative work on the science and technology of geologic disposal of high-level nuclear wastes and fissile-containing materials. Three different types of integrated technical activities in Russia are employed to focus and organize a Department of Energy (DOE) Office of Civilian Radioactive Waste Management (RW) FY00 initiative. We have specified the items for initial negotiations with the Russians for start-up activities in FY99 and early FY00. These first interactions will generate other activities which, by utilizing Russia�s unique capabilities, may assist us in the development and validation of the US geologic repository program. The current International Science and Technology Center (ISTC) cooperative study of 30years of heat effects on underground hardrock rock media at the closed city of Krasnoyarsk-26 (Zheleznorgorsk) is but one example of such a Russian geologic repository analogue project that may assist the US geologic repository program

Coronal structure of the cTTS V2129 Oph

The nature of the magnetic coupling between T Tauri stars and their disks determines not only the mass accretion process but possibly the spin evolution of the central star. We have taken a recently-published surface magnetogram of one moderately-accreting T Tauri star (V2129 Oph) and used it to extrapolate the geometry of its large-scale field. We determine the structure of the open (wind-bearing) field lines, the closed (X-ray bright) field lines and those potentially accreting field lines that pass through the equatorial plane inside the Keplerian co-rotation radius. We consider a series of models in which the stellar magnetic field is opened up by the outward pressure of the hot coronal gas at a range of radii. As this radius is increased, accretion takes place along simpler field structures and impacts on fewer sites at the stellar surface. This is consistent with the observed variation in the Ca II IRT and HeI lines which suggests that accretion in the visible hemisphere is confined to a single high-latitude spot. By determining the density and velocity of the accretion flows, we find that in order to have most of the total mass accretion rate impacting on a single high-latitude region we need disk material to accrete from approximately 7R*, close to the Keplerian co-rotation radius at 6.8R*. We also calculate the coronal density and X-ray emission measure. We find that both the magnitude and rotational modulation of the emission measure increase as the source surface is increased. For the field structure of V2129 Oph which is dominantly octupolar, the emission forms a bright, high-latitude ring that is always in view as the star rotates. Since the accretion funnels are not dense enough to cause significant scattering of coronal X-ray photons, they provide only a low rotational modulation of around 10% at most.Comment: 10 pages, 9 figure

Development of a Comprehensive Plan for Scientific Research, Exploration, and Design: Creation of an Undergroung Radioactive Waste Isloation Facility at the Nizhnekansky Rock Massif

ISTC Partner Project No.2377, ''Development of a General Research and Survey Plan to Create an Underground RW Isolation Facility in Nizhnekansky Massif'', funded a group of key Russian experts in geologic disposal, primarily at Federal State Unitary Enterprise All-Russian Design and Research Institute of Engineering Production (VNIPIPT) and Mining Chemical Combine Krasnoyarsk-26 (MCC K-26) (Reference 1). The activities under the ISTC Partner Project were targeted to the creation of an underground research laboratory which was to justify the acceptability of the geologic conditions for ultimate isolation of high-level waste in Russia. In parallel to this project work was also under way with Minatom's financial support to characterize alternative sections of the Nizhnekansky granitoid rock massif near the MCC K-26 site to justify the possibility of creating an underground facility for long-term or ultimate isolation of radioactive waste (RW) and spent nuclear fuel (SNF). (Reference 2) The result was a synergistic, integrated set of activities several years that advanced the geologic repository site characterization and development of a proposed underground research laboratory better than could have been expected with only the limited funds from ISTC Partner Project No.2377 funded by the U.S. DOE-RW. There were four objectives of this ISTC Partner Project 2377 geologic disposal work: (1) Generalize and analyze all research work done previously at the Nizhnekansky granitoid massif by various organizations; (2) Prepare and issue a declaration of intent (DOI) for proceeding with an underground research laboratory in a granite massif near the MCC K-26 site. (The DOI is similar to a Record of Decision in U.S. terminology). (3) Proceeding from the data obtained as a result of scientific research and exploration and design activities, prepare a justification of investment (JOI) for an underground research laboratory in as much detail as the available site characterization data allow. Consider the possibility of the substantiated selection of a specific site for the underground laboratory at this stage. (The JOI is similar to an advanced conceptual design or preliminary design in U.S. terminology). (4) Perform a preliminary safety assessment of the geologic isolation of radioactive waste and unreprocessable spent nuclear fuel (SNF) in the Nizhnekansky massif. Significant progress has been made toward fulfilling the joint project objectives. The results were documented in a series of quarterly reports and one final report over a period of {approx}2 3/4 years

A sensitivity study on the mechanical properties of interface elements adopted in finite element analyses to simulate the interaction between soil and laterally loaded piles

An increasing number of offshore energy structures have been built recently on driven piles, ranging from jack- et piles with typical length-to-diameter (L/D) ratios of 10-40 to monopiles with far lower L/D ratios. The load-displacement behaviour of these foundations can be investigated by means of Finite Element (FE) analyses, for instance following the design methodology developed by the PISA Joint Industry Project (JIP). A challenging aspect of the modelling, for piles loaded either axially or laterally, is the simulation of the behaviour at the soil-pile interface with the adoption of suitable formulations for the interface elements and with representative mechanical properties. This paper presents a sensitivity study conducted on both the elastic and plastic properties of interface elements adopted in FE analyses of laterally loaded piles driven in chalk. The study benefited from the extensive field and laboratory test results collected during the ALPACA JIP and the corresponding pile tests. The aim of the paper is to provide guidance for numerical modelling on the selection of the most appropriate mechanical properties of interface elements to be used in the analyses of soil-pile interaction under lateral loading
